ESA: Epidemiological Update On H5N8/H5N5 In Europe

#12,159

The resource center of Epidemiosurveillance Santé Animalehas published an updated European-wide summary of HPAI H5's progress across Europe, which now includes recent detections of HPAI H5N5 as well as H5N8.

Excerpts from a much larger (translated) report follow. Note: Translation software often introduces formatting errors when dealing with PDFs. While far from perfect, I'm hoping I've cleaned those up enough to make this report legible.

Two highly pathogenic avian influenza (HPAI) viruses - H5N5 and H5N8 - circulate Currently in Europe. The ADNS tool has not been adapted to the notification of new Subtypes H5N8 and H5N5, leading countries to notify outbreaks as "H5Nx", with Possibility of adding a free comment to the subtype, which some countries do. In Taking these comments into account, the ADNS declarations are distributed as follows: H5Nx (N = 197), H5N5 (n = 5), H5N8 (n = 786), and mixed H5N5 / H5N8 (n = 1). HPAI iruses are Therefore treated in their entirety in this note.

Several countries reported the presence of H5N5 subtype virus in avifauna (1 case Montenegro, 3 in Italy, and 1 in Croatia). In addition, the Netherlands reported a mixed case Of H5N8 / H5N5 infection in wild birds.

Since the last update on January 16, 122 new HPAI outbreaks have been reported Reported in Europe (EU plus Switzerland), mainly in Germany (34 households in avifauna) And in Slovakia (14 H5N8 households in avifauna). A first case of H5Nx in avifauna Captive was reported in Bulgaria (two swans and a white pelican in a zoo in Sofia).

The Total number of outbreaks and cases of notified HPAI continues to increase and is now 1083 (compared with 961 last week) of which 525 in wild birds (61 species 542 in breeding and 16 in captive avifauna (Tables 1 and 2).

The interactive map of HPAI homes is available on the ESA Platform website ( link ).

The IAHP situation in France is detailed in the note dated 16 January ( link ).

The HP H5N8 virus is also present beyond Europe. After being detected in Israel, Egypt, Tunisia, Iran, the Russian Federation, Ukraine, South Korea,Nigeria, Chinese Taipei and Uganda, its presence was reported in Kuwait

The mortality reported in breeding varies according to the species, but also Within a single species, and is available only for a limited number of households. For mono-specific farming, the mortality ranges from 0.06 to 33% of the species Gallus gallus, around 20% in turkey farms (but with a mortality rate 100% reported in a home in France), and from 0 to 70% in palmipeds. In spite of The caution required in interpretation (time of intervention in relation to Infection, epidemiologically linked breeding which could be at the very beginning of infection, Etc.), it should be noted that this strain appears to have an unusual virulence in Breeding palmipeds.

The 61 different species of birds infected in the avifauna in Europe with theirFamilies are:
